Seven grains of Pt-Fe alloy from three creek locations in Yukon were analyzed for their major and trace-element composition. Electron microprobe analysis revealed elevated levels of Pd, Rh, Ir, and Cu, and the grains host inclusions of various PGM species and silicate-melt. The trace element composition of silicate inclusions, determined via laser ablation ICP-MS, shows notable enrichment in large ion lithophile elements.
Use Cases
- Identify source rock types based on trace element enrichment patterns in silicate inclusions.
- Correlate platinum-group mineral compositions with specific geological settings like Alaskan-type mineralization.
- Study the association of Pt-Fe alloy grains with micro-inclusions of various PGM species.
Strengths
- Analysis includes results from electron microprobe and laser ablation ICP-MS for seven specific grains.
- Data includes specific geographic references to three creek locations and map areas in Yukon.
- The description provides a detailed geological inference about a subduction-related origin.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to the specific Yukon placers sampled.
